Anti-KCNE2 antibodies are used in the immunodetection of the protein potassium voltage-gated channel subfamily E regulatory subunit 2. In humans, the canonical protein has a reported length of 123 amino acid residues and a mass of 14.5 kDa. Its subcellular localization is in the cell membrane. It is reported to be highly expressed in the brain, heart, skeletal muscle, pancreas, placenta, kidney, colon and thymus. A member of the Potassium channel KCNE protein family, KCNE2 is reported to be an ancillary protein that assembles as a beta subunit with a voltage-gated potassium channel complex of pore-forming alpha subunits. Synonyms for this target antigen include LQT5, LQT6, MIRP1, potassium voltage-gated channel subfamily E member 2, cardiac voltage-gated potassium channel accessory subunit 2, and ATFB4. KCNE2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of KCNE2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
